Yeah, I go and done this pic, I use 3D thing and Photoshop and it turn out okay by my thinking.
It started off as me making a chainlink fence in 3D Studio MAX for my game, then the fence got bigger, a floor and background got added, along with a little scenery, then I added the characters which I'd already modelled bloody ages ago. Then I loaded it into Photoshop and made it grungy and 'artistic'.
